My invention is addressed to the provision of cartons with recessedplatforms adapted to hold resilientlysuch a fragile object as anincandescent electric lamp.

The platforms are usually cut out to accommodate'a part of the bulbportion of the lamp and also a portion of the base. Platforms have beenplaced or pasted into ordinary cartons, but the number of parts and thenumber of operations, and the expense incident to the use of suchcartons has made it advisable to provide a structure in which theplatforms are integral. In a co-pending application in my name, SerialNo. 284,341, filed June 11, 1928, I have described a type of lamp cartonwith integral platforms. The cartonis suitable for machine formation andpasting. So far as I am aware, however, there has never been a type ofcarton with integral recessed platforms which could be set up by a handor machine operation without pasting, and which, when so set up wouldpresent a stable structure having a tuck end flap for closing and readyto receive a fragile article.

Primarily, the object of my invention therefor, is to provide a cartonwith integral recessed panels, which may be set up without any pastingat all, and when set up holds its shape and is not subject 'to losingits form upon the opening of a single flap.

These and other objects of my invention, which I shall hereinafter setforth or which will be apparent to one skilled in the art upon readingthese specifications, I accomplish by that certain constructionandarrangement of parts of which I shall now describe a preferredembodiment.

In the drawings:

Figure 1 gives a plan view of my carton blank.

Figure 2 is a perspective view thereof, showing one of the recessedplatforms in partially set up position Figure 3 1s a view of my set upcarton in open position.

Figure 4 is a view of the closed carton.

Figure'5 is a sectional view through the carton taken along the lines a,a in Figure 4.

In my carton I provide a blank having 1929. Serial No. 373,123.

articulated members consisting of a bottom, side members 2 and 3, and atop 4, the top having a tuck end flap. Lines of cut in Figure 1 areindicated as solid, and lines of score as dotted. To one of the sides llhinge plat= forms 6 and 7 by means of articulated plat form holdingmembers-8 and 9, and about the platforms on the remaining three sidesare platform flaps .10 and 10a. The platforms may be perforated bysuit-able holes 11 and 12, as shown.

Upon the ends of the other side member, which in Figure 1 is the side 2,I provide flaps 13 and 14 which are locln'ng flaps to hold the carton inassembly. These flaps are provided with tongues 15 and 16, and theplatforms in the line of score adjacent the outermost platform flaps areprovided with cuts or slits 17 and 18, into which the tongues 15 and 16are adapted to enter.

. Referring now to Figure 2 it will be seen how the platforms areadapted to fold inwardly in setting up the box.

lln a companion case, Serial No. 392,451, filedSept. 13, 1929, I havedescribed a machine suitable for the settin up of this carton, which isadapted to pert orm, in the same or in a difierent sequence, the stepswhich I shall now describe. Reference is made to this application; butmy carton is adapted to hand setting up, if desired, and need not besetup on a machine. Figure 2 shows the platform 7 extending at rightangles to the side 3, the platform support 8 lying along the said side.Similarly, the platform 6 will be folded into position with the support9 lying along the side 3, the bottom 1 will be bent up to lieialong thebottom edges of the platforms 6 and 7, and afterward the side 2 will befolded over parallel with the side 3. The platform flaps 10 and 10a willlie along and parallel to the respective side and bottom portions of thecarton, and among other functions serve to stifien the platforms.

Then the flaps 13 and 14 are bent over so as to extend along theoutermost platform flaps in such a way that the platform flaps 10a liebetween the flaps 13 and 14, and the side 2 of the carton. The tongues15 and 16 will then be caused t9 enter the slits 17 and 18, and the setup carton when placed over upon its bottom 1, will have the appearanceshown in Figure 3. It will be seen that the carton retains a stable, setup shape even though the top is open. This is not characteristic of anyunglued platform carton of which I have knowledge. Furthermore, it willbe observed that spaces 19 and 20 lie between the side 2 and theadjacent platform flaps. These spaces are adapted to receive and bindthe tuck end flap 5, when the cart-on is closed as shown in Figure 4.

In the sectional view of Figure 5 may be seen to somewhat betteradvantage the relation of the parts which hold the platforms 6 and 7 inposition. It will be clear how the flaps 13 and 1 1 overlie and enclosethe platform flaps 10 adjacent the side 2, and how the tongues 15 and 16extend throu h the slots, locking the structure in shape. lamp or otherarticle 19 renders the lock more effective by preventing the inwardcollapse of the platforms.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is

1. In a carton, a' blank comprising a bottom, two sides, a top, and atuck end flap thereon, recessed platforms hinged to either end of theside adjacent said top by means of platform supporting members, latformflaps on the other sides of said p atforms, locking flaps on the ends ofthe opposite side of said carton, said locking flaps adapt ed to locksaid recessed panels in position when said carton is set up, and toleave spaces between the platform flaps and said opposite side for theinsertion and holding of said tuck end flaps.

2. In a carton blank comprising a bottom, two sides, a top, and a tuckend flap thereon recessed platforms hinged to either end 0 the sideadjacent said top by means of platform supporting members, platformflaps on the other sides of said platforms, locking flaps on the ends ofthe opposite side of said carton, said locking flaps adapted to locksaid recessed panels in position when said carton is set up, and toleave spaces between the platform flaps and said opposite side for theinsertion and holding of said tuck end flaps, said locking meanscomprising tongues on said locking flaps and slots in the line ofarticulation between said platforms and said platform flaps.

3. In a carton, a bottom, sides joining opposite lateral edges of thebottom, platform members each having a foldable attachment to arespective end edge of one of said sides and having flaps at its otherthree edges, a lid hinged to the upper lateral edge of said side, a flapalong the outer edge of said lid, and locking flaps joining therespective end edges of the opposite side, locking across the adjacentplatform edges and V flaps, said lid having its flaps entering behindplatform flaps at corners adjoining the locln'ng by said locking flaps.

4. In a carton, a bottom, sides joining 0pposite lateral edges of saidbottom, platform members each having a foldable attachment to arespective end edge of one of said sides and having flaps at its otherthree ed es, a lid hinged to the upper lateral ed e 0 said side, a flapalong the outer edge 0 said lid, and locking flaps joining therespective end edges of the opposite side, locking across adj acentplatform flaps, the outer platform flaps having slits at their junctionswith the platforms, and the locking flaps having tongues enterin saidslits, the lid flap entering behind plat orm flaps at corners adjoiningthe locking flaps and their tongues.
